    Just as an update; I took the new fuel water separator off and dumped gas into a clear container to see if it had water in it. Appears to be fine, no water. Sprayed the carburetor well with carb cleaner. Let it soak. Took it for a drive. Did get up on plane as long as I was slow with...

    Yes. I just stopped in the local shop ND they suggested a carb rebuild. Said it could be the secondary pump in the carb. Will pick up a kit today. He said the anti syphon valve wouldn't let any gas get thru if it was that??
